Copy Common Cells And Variable Range From Multiple Worksheets To Single Master Workbook

Basically, i have a common workbook template that is used by multiple users across the business to request a cost for numerous new products.

Within the template, there is a common section at the top, where specific project information is entered. There is also a table beneath where 1 or many products can be entered, with specific information relating to that product in the same row.

All the submitted requests are uploaded via an email attachment, to a particular sharepoint directory.

What i would like to do in the master workbook is the following:-

1. Open in turn every uploaded workbook within the sharepoint directory and copy the following cells into the master workbook, each in it's own row (or next available), with the data in adjacent cells.... 1st cell to enter data is $B6.

Cells to copy from each sheet:

Common info contained within cells:
$DG$2,$N$11,$N$12,$N$19,$N$13,$AO$7,$AO$8,$AO$9,$AO$10,$AO$11,$AO$12,$AO$12,$AO$13,$AO$14,$BO$8,$BO$11,$BO$14

Product specific info: $U37, $AD37, $AH37, $DH37, $C37, $O37

Depending on the number of products requested, we need to repeat (loop?) until it finds the next blank row in the table. I have hidden a blank row in the table, so there will always be one!

All of the common information needs to be included for each product specific entry.

For each file, once the upload has been completed, i would like the file to be moved to another "archive" directory.

I have attached the template for information. The master workbook is still in development so can't share currently.
